Another new twist in the science of scofflaw neutrinos: A second Italian physics group now says they are not moving faster than light after all. So the foundations of modern physics appear safe for now — but this debate will likely not be settled for some time.
The physicists who claimed to see neutrinos moving faster than light are moving quickly to replicate their experiment, hoping to substantiate their results before submitting them for publication. Since announcing their bizarre, seemingly impossible findings last month, physicists around the world have offered a few possible explanations. But perhaps the best test will be a retest.
Physicists working at the Large Hadron Collider report that after a series of tests, they have not seen any mini black holes, to the chagrin of string theorists and the relief of disaster theorists.
Researchers working on the Compact Muon Solenoid team have been crunching numbers to test a form of string theory that calls for the creation and instant evaporation of miniature black holes. They report that the telltale signs of these black holes are disappointingly absent, however.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
